This `operates the engine 21 to close door 13. The inagnet'valve 106 is of thesaine'charac ter ,as magnet valve 102. It isfto be noted that the door adjacent the control pointis under the control of the operatorindependently of. the position of the trap 'at the co `nioo trol point. In otherwords the pole switches u and circuits are arranged so that tlie'door adjacent tlie coiitrol'pointinay beoperated'in- Y' fdependcntly ofthe trap.

By closing tlie'push buttonniarked rl, the following circuit -is established: from the positive side of the current sour-ce through push button H, wire 107, the contact on drum switch 5, .wire26, wire 108', ferrule 10, wire Y 113, Contact on-drum switch 6, wire-11st',

'After .all the 1105". openail the-doors which'have theirA traps passengers 'have departed `troni the train and b'oardedthe train, the operator 'may' then push the lower button marked c, and all doors which are open will close except the door 13. Closure of pushbutton 0 establishes' the following,` circuit: from the positive sideof the current source through push button c', wire 111, the control or druin switch, 5, wire 27, wire 112', the contact on Ydrum invitch` 6, wire 105, closinginagnet 106 and thence tojground Vat 103."l`his 'causes door 16 to close and .similarly all other doors-that are open become closed. It.

the station had been a low level station, the

train conductors would then raise all the .traps and when the operator pressed the button inarled L, all the doors would open,

whose traps had` been raised. When'switch"v L is closedf'the following circuit is estab- Y o lished: from the positive side of the vcurrent source through buttonL, wire 109, ,the .con-

` tact on druin switch 5, wire 25,the V"Contact on drum Vswitch 6, connected to wire 25, wire 25 to' the nextv car,`the contact on drinnl Vswitch 7 connected to wire 25, wire 25 on ear B, wire 5110, ferrule 11', wire 113, the contact on drum switch ,connected to wire 113, wire 11%, opening, magnet Valve 102 and thence to ground at 103". f This opens ydoor 17 and similarly all.V other doors having their tra'psfup.l ltv is to be understood that the respective pole switches` are' properly positioned in vaccordance with the positions of thelcorresp'onding'traps.` i However, it for any reasonl some particular trapl had not been raisedv that doorwill not openV when the low level button is pushed.

Here a02-in when the lower button marked'- V :p .1 f c is depressed all the doors which are open will close. The button inarlred C directly aboreit will 'close only the door adjacent the point of control.A By the ioregoingdescription, itV is eviiil'ent 'that the operator may control all the doors reinot'e troni .his station regardless .of thepositionA of his trap, but low level doors will not be opened, vwhere 'the traps are down, nor will highA level doors `be opened where the traps are up.
